Abstract

PROBLEM TO BE SOLVED: To provide a rail rolling stock which is capable of absorbing impact energy and is safe. SOLUTION: A front unit 100 is located at a front edge of the car. Its floor comprises a hollow material 200 constituting a buffer unit 200. The buffer unit comprises an upper and a lower buffer devices 200, 200. An annealed hollow material is used for a hollow type member 210. A longitudinal direction of the hollow members 210 is a longitudinal direction of the car body. Multiple hollow members 210 are laid out in a cross direction and jointed by a friction- stirring joint. When the impact load is imposed, the hollow members 210 are deformed into bellows and absorbs impact force. At that time, the impact force is applied upon the friction-stirring joint unit, however, thanks to the joint, any cracks do not occur and the deformation of the hollow members 210 into bellows is not hindered.

を示す。Here, the impact force relaxation characteristics of the hollow shape member 120 will be described. When a compressive load is applied, the behavior of load-deformation as shown in FIG. 10 is exhibited. Depending on the material properties,
As shown in FIG. 11, a material i having high strength such as tensile strength and proof stress and small elongation (brittle), a material iii having low strength but good elongation (viscous), and characteristics intermediate between the above materials i and iii Material ii shown is possible. In the material of the curve indicated by X (X 1 , X 2 ) in FIG. 10 (the material corresponding to the strength characteristic I in FIG. 11), the withstand load becomes large, but the withstand load sharply decreases after exceeding the maximum load. Will be done. On the other hand, the strength is low,
A material having a large elongation (a material corresponding to the strength characteristic iii in FIG. 11) has a characteristic that the maximum withstand load becomes low as shown by the curve indicated by Y in FIG. 10, but the subsequent withstand load does not suddenly decrease.

処理することによって容易に得ることができる。The range of the shaded portion shown in the example of the Y curve shows the breaking energy of this material. Comparing the X and Y curves, it can be seen that the material having moderate strength and good elongation (in this case, the material having the Y curve) has a higher fracture energy due to the deformation behavior after the maximum load resistance. It is important to select a material having such strength characteristics Y as the buffer member B. A material having a Y curve can be easily obtained by subjecting an extruded shape member to, for example, an O material treatment.

とができることになる。In the case of the X curve, since the strength of the material is high and the elongation is small, the elongation cannot follow the imbalance of the stress in the member cross section, resulting in partial fracture.
The load bearing capacity will drop sharply. On the other hand, in the case of the Y curve, the maximum load resistance of the member is lower than in the case of the X curve, but since the material has a large elongation, it is partially plastically deformed due to the variation in the stress in the cross section (the elongation can follow. Therefore, it is possible to largely deform while maintaining a certain amount of load resistance without causing a sudden decrease in load resistance.

る。Therefore, the hollow shape member 210 is deformed into a bellows shape, and the impact applied to the vehicle body is alleviated. further,
Since it is composed of the hollow shape member 210, its in-plane bending rigidity and out-of-plane bending rigidity are higher than that of a general thin plate structure, and it is a composite structure composed of two face plates and diagonal members. Also, it has the effect of having a high breaking energy absorption characteristic against a compressive load (per unit flat area).

衝撃エネルギーを吸収できる。The plurality of hollow shape members 210, 210 are joined by friction stir welding along the longitudinal direction of the vehicle body to which the impact is applied. If this joint was arc welded,
The welded part breaks, making it difficult to deform into a bellows shape,
Energy absorption characteristics are reduced. This can be understood from the fact that in the case of arc welding, the impact value of the welded portion is much lower than the impact value of the base metal. However, the impact value of the friction stir welded portion is higher than that of the arc welded portion, and the welded portion does not break. It is considered that this is because the metal structure of the joint becomes fine due to the friction stir welding and the energy absorption value becomes high. Therefore, when friction stir welding is performed, each hollow shape member is deformed as prescribed,
Can absorb impact energy.
